Stomach pain after c section

Dana • Wife: 7/22/17 💍🧖🏾‍♀️ mother: 10/22/19🤰🏽

I had a c section on Tuesday and today my stomach is sore to the touch. Does it suppose to be like that? This is my first child so I’m not sure if its common or not. I also have back pain from my epidural. Is that common also? Please advise
